The fundamental concepts of modern digital VLSI circuit design using CMOS technology with an emphasis on “hands-on” IC design using CAD tools. An overview of CMOS technology. Combinational and sequential logic circuits including transistor level design of logic gates at the device and layout level. Clocking methods. Memory design and memory decode logic. Digital IC design flow. Hardware Description Languages (VHDL/Verilog), architectural aspects of a VHDL, synthesised VHDL on physical hardware. Low-power logic families such as DCVS and Adiabatic Logic and discuss the implications of modern methods on circuit design. Chip level design methodologies (full-custom, semi-custom and standard cell) exploration.
